Void have an LTS kernel metapackage which is currently tracking the 4.14 branch and also offer 4.4, 4.9 & 4.19. Their kernels are already de-blobbed.

Devuan's kernels are also de-blobbed, no need to rely on third-party repositories.

Are you sure about that? I've just added bullseye to my buster box to check:

~$ apt policy thunderbird
thunderbird:
  Installed: (none)
  Candidate: 1:68.12.0-1
  Version table:
     1:68.12.0-1 500
        500 https://cdn-aws.deb.debian.org/debian bullseye/main amd64 Packages
     1:68.12.0-1~deb10u1 500
        500 https://cdn-aws.deb.debian.org/debian buster/main amd64 Packages
        500 https://cdn-aws.deb.debian.org/debian-security buster/updates/main amd64 Packages
~$

How about

# echo disk > /sys/power/state

EDIT: see also https://www.kernel.org/doc/Documentatio … states.txt

^ Looks like the OP is already using the legacy iptables version.

And anyway there's no need to uninstall nftables:

# update-alternatives --set iptables /usr/sbin/iptables-legacy

For archives you should use archival Blu-Rays or DVDs. Hard drives don't last long.

That only starts the agent once.

If the package is installed then Xfce should autostart it via /etc/xdg/autostart/polkit-gnome-authentication-agent-1.desktop so check for ~/.config/autostart/polkit-gnome-authentication-agent-1.desktop — that might be overriding it.

EDIT: and your kernels are outdated, you should install the metapackge:

# apt install linux-image-amd64/beowulf-backports

You could grab the DMO source and modify debian/control so the dependencies are satisfied by the beowulf Kodi version but the add-on might not work for that.

It is possible to exclude programs from compton's attentions, that might allow you to run a compositor without breaking thunar & palemoon: https://github.com/chjj/compton/issues/182

There is also the newer picom fork, which I have packaged up for De??an (needs updating though, I'll probably do that this weekend): https://software.opensuse.org//download … kage=picom

Or perhaps just use something like xcompmgr if you just want simple effects.

Do you have any polkit authentication agents running?

pgrep -a polkit

EDIT: if this happened after an update then we should probably also see your sources:

apt policy

Check again, my command just toggles the "sort-directories-first" option in the section suggested by PedroReina.

¯\_(ツ)_/¯

^ This.

Or from the command line:

gsettings set org.gtk.Settings.FileChooser sort-directories-first true

With which program are you attempting this operation?
